Default Leaky accel pump

So after like a year of other problems I finally solved now I notice when I spin the throttle very little gas goes through the accel jet and when I release it mostly comes out the hole for the pump lever.
I figure I can just buy a carb rebuild kit and that should solve it up good. However, I have the 44mm SE CV carb and all I see is stuff for 883's or the 40mm. Although my assumption with playing on that carb for so many years now it seems to be identical to the 40mm in every way just a slightly larger bore. So would this kit from Amazon work?

Tried to add a vid but mp4 isn't allowed apparently, so here is a snap of the fuel spurting out.

Rebuild it. The ethanol deteriorates the rubber diaphragm.

That is what I said I was planning to do, the main question was will the rebuild kit I linked work for my 44mm carb?
Harley doesn't sell many carb parts anymore and 90% of carb related is listed as discontinued. Including the rebuild kit

Yes, the accelerator pump is the same all the way back to the 38mm Keihin butterfly version. Of course there are different bowl gaskets.

The main differences (best I can remember) are the vacuum slide, jet needle and needle jet. Everything else should interchange with a CV40.

So all you really need is a common accelerator pump kit. You don't need to drop the bowl to replace that...

I didn't get that from your post sorry. But there are rebuild kits everywhere not just Harley, hell for the most part dealers don't even work on older bikes anymore.

or email them. I've had good luck buying from them. Good choices for upgrades also.
